Dynamical locality of the nonminimally coupled scalar field and enlarged algebra of Wick polynomials

open access: yes, 2012
We discuss dynamical locality in two locally covariant quantum field theories, the nonminimally coupled scalar field and the enlarged algebra of Wick polynomials.

Optimization of net power density in Reverse Electrodialysis [PDF]

open access: yes, 2019
Reverse Electrodialysis (RED) extracts electrical energy from the salinity difference between two solutions using selective ion exchange membranes. In RED, conditions yielding a large net power density (NPD) are generally desired, due to the still large ...

Assisted reverse electrodialysis : principles, mechanisms, and potential [PDF]

open access: yes, 2018
Although seawater reverse osmosis (RO) is nearing its thermodynamic minimum energy limit, it is still an energy-intensive process, requiring 2–3 kWh/m³ at a recovery of 50%.

Study of the auto-ignition phenomenon of PRFs under HCCI conditions in a RCEM by means of spectroscopy [PDF]

open access: yesApplied Energy, 2016
An investigation of the effects of contour conditions and fuel properties on the auto-ignition and combustion process under HCCI conditions is presented in this study. A parametric variation of initial temperature, intake pressure, compression ratio, oxygen concentration and equivalence ratio has been carried out for Primary Reference Fuels in a Rapid ...

Review: Hormone Pregnancy Tests Were Teratogenic by the Same Failed Abortion and Hypoxia‐Related Mechanism as Misoprostol

open access: yesBirth Defects Research, Volume 117, Issue 3, March 2025.
ABSTRACT Introduction Hormone pregnancy tests (HPTs), containing synthetic progesterone and oestrogen, were used to diagnose pregnancy in the 1950s to early 1980s. An existing pregnancy was purported to be unaffected while expulsion of the uterine lining (withdrawal bleed) was supposed to occur if the woman was not pregnant.

Energetic and Socioeconomic Justification for Solar-Powered Desalination Technology for Rural Indian Villages [PDF]

open access: yes, 2014
This paper provides justification for solar-powered electrodialysis desalination systems for rural Indian villages. It is estimated that 11% of India’s 800 million people living in rural areas do not have access to an improved water source. If the source’

Extracting Site Effects From P‐wave spectra: Application of Cluster‐Event Method 2 (CEM2) in the Tohoku Region, Japan

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 1, January 2025.
Abstract Theories related to the Earth's attenuation effect and earthquake source properties predict a similar spectral falloff of body waves, creating severe trade‐off problems when determining these two processes from waveform spectra. Previous efforts attempted to suppress this trade‐off by either applying an empirical Green's function or conducting

Assisted reverse electrodialysis : a novel technique to decrease reverse osmosis energy demand [PDF]

open access: yes, 2016
Assisted reverse electrodialysis (ARED) was introduced as a pre-desalination technique for seawater reverse osmosis (RO) for drinking water production. ARED is comparable to an additional applied pressure along the osmotic pressure in pressure assisted ...
